CHIPPEWA COUNTY -- An inmate has been sentenced to life in prison for carjacking in the foiled Upper Peninsula prison break that led to a corrections officer’s fatal shooting of Muskegon-area mass murderer Seth Privacky.

A Chippewa County 50th Circuit judge last week sentenced Andrew Joseph Ross, 25, for his part in the attempted escape July 25 from Kinross Correctional Facility, according to Chippewa County Prosecutor Brian A. Peppler.

Ross pleaded guilty to the charge Aug. 31. He is lodged at Marquette Branch Prison as a Level V inmate, meaning maximum security.

Ross already was serving a sentence of 18 years nine months to 40 years for three counts of second-degree murder committed in 2003 in Macomb County.

Peppler said earlier that charges against the third inmate, Brian Lee Davidson, 31, would not be filed because Davidson already is serving life in prison without chance of parole.

Brian Davidson

Davidson was convicted of first-degree murder in Kent County in 2003 for the random killing of a bicyclist. He also is lodged at Marquette at Level V security.

The three convicted murderers overpowered and injured a semi-truck driver, hijacked the truck and drove it through the double fence of Kinross, a medium-security prison near Sault Ste. Marie.

Authorities said Privacky, who was 30, was running from the prison toward a health care center across the street when the corrections officer shot him. Peppler earlier cleared and commended that officer.

Ross and Davidson surrendered after Privacky was shot.

Privacky committed what may have been Muskegon County’s worst-ever mass murder when he was 18.

Seth Privacky

He was convicted of 10 felony counts, including five for murder, stemming from the Nov. 29, 1998, slaying of his mother, Linda Privacky, 49; father, Stephen Privacky, 50; brother, Jedediah Privacky, 19; grandfather, John Privacky, 78; and April Boss, 19, who was Jedediah Privacky’s girlfriend. All were shot execution-style.

The crime occurred on Thanksgiving weekend in the family’s home on Riley-Thompson Road in Dalton Township.
